Refined like gold in fires,refinery,oil refinery!
Actually,oil comes from algae ponds that filled in with sand then covered over by clay.then heat cracked the oil from the algae.we could do the same thing with old oil wells.pump algae into them and wait for heat and pressure to crack it.i gave this idea to olbummer when the whitehouse was looking for ideas.giant algae ponds using co2 pumped from coal and natural gas power plants vented into algae ponds then algae pumped into wells.the algae would absorb and convert most of the co2.
